American Ebola Victims 'Slightly Improving' as Family Issues Statement on Faith and Gratitude for Prayers (VIDEO)

The two Americans diagnosed with Ebola after working in Liberia are both fervently praying to God for deliverance, and now they are reportedly improving as well. Dr. Kent Brantly and Nancy Writebol were both infected while working as Christian missionaries and their faith is helping them through their ordeal.

"She's stable," Nancy's son Jeremy told "Today." "She's fighting through it and continuing to express a few symptoms but she's able to move around on her own. She's working real hard to get through this."

Writebol and her husband David have served as missionaries for over 15 years and are still together in Liberia. David is only allowed to see his wife through a window, lest he be infected as well. Their church in Charlotte, North Carolina held a prayer service for the couple.

Meanwhile, Dr. Kent Brantly is currently "up working on his computer, talking with people. He is moving, he is active. He is interactive and we are pleased with that," Dr. Bruce Johnson, President of SIM USA, told MailOnline. "This is not a light situation – this is a very serious situation but we are encouraged by how they (Brantly and Writebol) are doing so far."

"Her husband David seems strong," Johnson added of Writebol. "He is handling this with faith but he is also realistic with Nancy and Kent."

Brantly was able to send an email to his friend, Dr. David McRay, with whom he worked at John Peter Smith Hospital in Texas.

"David, I think what I would like to say is thank you for all the prayers and messages of encouragement. I am praying fervently that God would help me survive this disease. Please continue to pray along with me, and pray for my friend Nancy, who is also very sick, and for the doctors who are taking care of us. Thank you all so much. Peace, Kent."

Brantly's wife Amber, who is in the U.S. with the couple's children, also expressed her own gratitude for all of those who are praying for her husband.

"We have a strong family unit within a stronger faith community that has given us incredible support," she wrote in a message left on the Samaritan Purse website. "As people with a deep faith in Jesus, we sincerely thank the thousands of people worldwide who have lifted up Kent and this dreadful situation in prayer. We continue to lean on that faith and take great consolation in our God in these times."
